| 摘 要： | 热固性环氧树脂涂层具有优良的防腐蚀性能,被广泛应用在各种恶劣环境中对管线进行防腐蚀保护.钻杆用内涂层的防腐蚀性能一直采用高压釜进行评价,此评价方法时间长,并且不能对涂层失效机理进行分析;因此,在高压釜评价涂层性能前,利用扫描电子显微镜对涂层表面的微观结构进行观察,分析了涂层的表面微观缺陷以及可能引起涂层失效的原因,最后...

| Abstract: | Thermoset epoxy coating is widely used to protect corrosion on pipeline in harsh environments because of excellent corrosion resistance.Performance evaluation of the inner coating for drill pipes has been evaluated by high pressure autoclave.But,such evaluation method needs a long time,and can not analyze the failure mechanism of coatings.So,we do the following research.First,we adopt microscopic analysis on the coating defects and the factors that may cause coating failure,Last,use the high pressure autocl... |
